Clinical signs included weight loss, abdominal pain, and defecating posture frequently. When the beagle dog defecated, no feces but cauliflower-like mass in rectum mucosa were found obviously. Digital radiographic and fecal detection were applied and then the cauliflower-like mass was incised. Histopathologic examination revealed that nematode larvae infiltrated in the tissue.
